Preface

i

Before you commence, please attentively read the following important discretions below. All

cautions and warnings on the equipment or in the manuals should be circumspectly noted

and reviewed.

Always ground yourself to prevent static electricity.Always ground yourself to prevent static electricity.

Aard jezelf altijd om statische elektriciteit te voorkomen.Aard jezelf altijd om statische elektriciteit te voorkomen.

• Firmly ground yourself at all times when installing or assembling the internal

components of the server. Most of electronic components in the server are highly

sensitive to electrical static discharge.

• Use a solid grounding wrist strap and distinctively place all electronic components in

static-shielded devices to prevent static. Grounding wrist straps can be purchased in

any electronic supply store.

• Confirm that the power source is turned off and then disconnect the power cords from

your system before performing any type of installation or manual servicing. A sudden

surge of power could severely damage the sensitive electronic components.

• Do not precipitously open the system’s top cover. If you must open the cover for

maintenance purposes, only a trained technician should be allowed to proceed this

action. Integrated circuits on computer boards are highly sensitive to static electricity.

Before operating a board or integrated circuit, touch an unpainted portion of the system

unit chassis for a couple of seconds to discharge any static electricity on your body.

Place the server in a stable environment. Place the server in a stable environment.

• Place this equipment on a stable surface when installing. A small mild drop or fall could

cause fatal injury to both the equipment and the person handling the equipment.

• Please keep this equipment away from humidity to prevent vast rust and disintegration.

• Carefully and accurately mount the equipment into the rack. Uneven mechanical

loading may lead to hazardous consequences.

• This equipment is to be installed for operation in an environment with maximum

ambient temperature below 35°C.

• Review the environment before performing any installation or servicing. Keep the

equipment away from hazardous and uneven grounds.

• This server must be installed only in Restricted Access Locations.

• Do not cover the openings of the system. The openings on the system are for air

convection, which intentionally protect the equipment from overheating.

• Never pour any liquid into ventilation openings of the system. This could cause

catastrophic fire or electrical shock.

Safety Instructions

ii

• Ensure that the voltage of the power source is within the specification on the label

when connecting the equipment to the power outlet. The current load and output power

of loads must be within the specification.

• This equipment must be firmly connected to reliable grounding before usage. Pay

special attention to power supplied other than direct connections, e.g. using of power

strips.

• Place the power cord out of the way of foot traffic. Do not place anything over the

power cord. The power cord must be rated for the product, voltage and current marked

on the product’s electrical ratings label. The voltage and current rating of the cord

should be greater than the voltage and current rating marked on the product.

Pay attention to hardware maintenance.Pay attention to hardware maintenance.

• If the equipment is not used for a long time, disconnect the equipment from mains to

avoid being damaged by transient over-voltage.

• Module and drive bays must not be empty. They must have a dummy cover.

• Never open the equipment without professional assistance. For safety reasons, only

qualified service personnel should open the equipment.

• If one of the following situations arise, the equipment should be checked and tested by

service personnel:

1. The power cord or plug is damaged.

2. Liquid has penetrated the equipment.

3. The equipment has been exposed to moisture.

4. The equipment does not work well or will not work according to its user manual.

5. The equipment has been dropped and/or damaged.

6. The equipment has obvious signs of breakage.

7. Please disconnect this equipment from the AC outlet before cleaning. Do not

use liquid or detergent for cleaning. The use of a moisture sheet or cloth is

recommended for cleaning.

CAUTION

The equipment intended for installation should be placed in Restricted Access Location.

CAUTION

There will be a risk of explosion if battery is replaced by an incorrect type. Dispose

of used batteries according to the instructions. After performing any installation or

servicing, make sure the enclosure is correct in position before turning on the power.

CAUTION

This unit may have more than one power supply. Disconnect all power sources before

maintenance to avoid electric shock.

Chapter 2� Hardware Setup

This chapter provides the graphic detail and basic instruction for hardware installation.

Turn off the system and unplug all peripheral devices before proceeding.

2�1 Central Processing Unit

The serverboard supports dual Xeon scalable processors and Socket P4 (LGA-4189).

2�1�1 Installation

To ensure a safe and easy setup, you need to prepare before installation:

 a T30 torque screwdriver

 ESD wrist strap/mat and conductive foam pad

 Safe and stable environment

CAUTION

The pins of the processor socket are vulnerable and easily susceptible to damage if ngers

or any foreign objects are pressed against them. Please keep the socket protective cover on

when the processor is not installed.

CAUTION

When unpacking a processor, hold the processor only by its edges to avoid touching the con-

tacts.

Standard Processor Assembly:

A standard processor assembly is comprised of 5 components: processor carrier,

processor, bolster plate assembly, socket and back plate.

 Attach the heat sink onto the CPU carrier. Hook the corners of the CPU carrier to the

back side of the heat sink.

 Install the assembled heat sink and CPU carrier onto the CPU socket. Please use a T-30

torque driver tighten the nuts in the four corners of the heat sink labeled in the order

1  2  3  4.

CAUTION

Failure to tighten the heat sink screws in the specified order may cause damage to the

processor socket assembly. Heat sink screws is recommended to be tightened to 8 in-

lbs torque, but can be tightened to 12 in-lbs torque according to the indicated order on

the top of the heatsink label.
